Abstract
A process for producing an electroluminescent device comprising a luminescent layer located between two electrodes formed on an insulating substrate wherein the luminescent layer is composed of a host material to which a luminescent center element is added and the host material is composed of an alkaline earth metal element of the Group II of the Periodic Table and an element of the Group VI, which process comprises forming the host material by chemical vapor deposition to react a gas of an organic compound containing the alkaline earth metal element of the Group II and a gas of a compound containing the element of the Group VI in a reactor, the gas of the organic compound containing the alkaline earth metal element of the Group II being formed from a cyclopentadienyl compound. By this process, EL devices can be produced with high reproducibility.
